Qi and Blood Stagnation

Qi and Blood Stagnation is a fundamental pathological syndrome in Traditional Chinese Medicine (TCM) rather than a specific molecular target such as a receptor or enzyme. It characterizes a state where the flow of 'Qi' (vital energy) is obstructed, which subsequently fails to promote healthy blood circulation, leading to 'Blood Stasis' (Xue Yu). Modern scientific investigations correlate this syndrome with physiological conditions including blood hyperviscosity, impaired microcirculation, vascular endothelial dysfunction, and chronic inflammation (PMID: 31102941, 28834469). As a systemic syndrome pattern, it is not classified under a single molecular family but is often managed using multi-component herbal therapies that target various pathways simultaneously. Common therapeutic interventions, such as Salvia miltiorrhiza, work by inhibiting platelet activation and improving blood flow via the modulation of nitric oxide signaling and inflammatory cytokines. In the context of drug development, it represents a complex phenotype rather than a single targetable protein, making it a focus of integrative medicine research for cardiovascular and oncological conditions (PMID: 25705353).
